Inclusion criteria
Inclusion criteria: Patients will be included in the study if they will have a predicted difficult airway as assessed by the presence of at least one of the following clinical predictors: mouth opening (interincisor distance) < 3.5 cm; thyromental distance < 6 cm, Mallampati score ¿ 3, limited mobility at the atlanto-occipital joint (< 15 ¿ ), according to Bellhouse & Dore.7 Mallampatti grade will be determined with the patient maximally protruding his tongue with the head in full extension during sitting position.8 Interincisor distance will be measured with the patient in sitting position, and thyromental distance will be measured from inside of the mentum to the thyroid cartilage with the head in full extension.9
Exclusion criteria
